' To all whom it may concern:

. Ini roveinent in Collapsible Receptacles, of

which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention ielates to collapsible receptacles more particularly intended foruse as lpails or buckets for conveying Water or other quid.

In order that the principles of the invention may be clearly understood, I have illustrated a single type or embodiment thereof in the accompanying drawings, wherein,-

Figure 1 is a plan view of the. sheet of paper oi the like from which the receptacle may be folded or formed, the paper being represented as scored to facilitate folding of the rece tacle into position for use and also for fo ding into the form shown in Fig. 4. Fig. .2 is a plan view of a similar sheet correspondingly scored and also provided with lateral flaps. Fig. 3 is a ers ective view of the receptacle in condition 'or use, the flaps being omitted; Fig. 4 is a perspective view of the receptacle after the same has been shaped for use and then folded into position for shi ment; Fig. 5 is a detail representing a mo ification of the means for securing the bail in position and Fig. 6 is a detail view of a further modification.

Referring more specifically to the single l type of the invention herein illustrated the sheet of paper, cloth or 'the like from which the rece tacle is formed is indicated at 1 in each of t ie figures. If paper be employed it may .be superiicially treated. to render it Waterproof by the use of paraffin or the like or the material from which the paper is made may be impregnated or otherwise treated with suitable material during the process of manufacture. If cloth such as inuslin or other material be employed, the same may be treated in similar manner. in Figs. 1 and 2 is scored .to provide a rectangular and preferably s uare basel portion 2, the sheet being suitab y scored to provide the sides 3, 4, 5 and 6, and corner portions 7, 8, 9 and 10. Each of the corner. portions is diagonally scored, as represented at 7', 8 9gand 10 and four` lines of scoring 11,

'portions 7, 8, 9 and 10, a pair of such opnen- The sheet shown v 12, 13 and 14 are provided parallel with the edges of the base 2 and the edges of the sheet and extending from edge to edge of the latter, such lines of scoring being herein represented as situated at equal distances from the edges of said base portion and the edges of the sheet. Moreover, each of the side portions 4. and 6 is provided with lines of scoring 15, 16, which meet diagonally disposed scoring lines 17, 18, 19, 20, extending from the corners of the base portlon 2 t0 such lines of scoring.

Preferably I provide a bail for the recepl tacle and may employ .any suitable means for attaching the same thereto. In the type of the invention illustrated in Fi s.' 1 and 2, I have represented openings 21, iaving preferably an enlarged circular portion and a narrow portion extending therefrom. Preferably such openings are provided upon the sides 3 and 5 and upon each of the corner ings being provided as shown -upon eac of such corner portions.

In folding the receptacle into position for u'se, the corner portions 7 and S, are folded upon their diagonal lines of scoring and Superim osed latwise against the outer surface of t e side 3, the corners 9 and 10 being similarly folded and superimposed against the outer surface of the side 5. Ii. this position of the parts the five openings 21 represented upon the upper portion of Figs. 1 or 2 A meet to provide a single reinforced opening for the attachment of the bail 22, as illustrated at 23 in Fig. 3, while the corresponding openings at the lower end of Figs.v 1 and 2, similarly meet as indicated at 24 in Fig. 3 to permit the attachment of the other end of the bail 22.' at opposite ends, as indicated at 25, the

knot being passed through the enlarged por- Preferably the bail is knotted.

y bail through the opening when the receptacle is in use.

Thesheets 1 may be shipped flatWiSe, as represented in Figs. 1 and 2 and superimposed. If desired, the receptacle may be assembled before shipment, as indicated in Fig. 3 and thereafter folded for shipment, or,

as is usually the case, after the receptacle has been used, it may be desirable to fold o`r collapse the same into compact form in order to save space. In order to collapse the receptacle after the saine is Ifolded into condition for use, I may fold the same, as indicated in Fig. 4, along either the line 11 or 13 represented in Figs. 1 and 2, in which case one of the sides to which the bail is attached is transversely folded and the opposite side is preferably superimposed flatwise thereupon, as indicated in said figure. If the assembled receptacle be folded along the line 11 into the form shown in Fig. 4, it will be apparent that since the corner portion 8 is positioned against the side 3, that portion of the scoring 12 embraced between its intersection with the scoring 11 and the scoring at the base of the side 3 and cover 8, will coincide with a portion of the scoring 11 where the same crosses the side 3, and hence the material of the receptacle will be folded along said coinciding scoring. The material of. the receptacle Will alsobe folded along that portion of the scoring 12 that is upon the wall 4, since the folding of the receptacle along the scoring 11, compels the folding thereof along the diagonal vlines 17 and 18, and hence along the adjacent portion of the scoring 12. What is here stated is correspondingly true of the scoring 14. It is apparent that if the receptacle be folded along the scoring 13 instead of the scoring 11, the material of the receptacle Will be folded along that portion of the scorings 12 and 14 that is between the scoring 13 and the scoring at the base of the side 5 and the corners 9 and 10.

In order to ship the sheets they may be folded as if to use the receptacles and then be further folded into the condition shown in Fig. 4, with or without attaching the bail thereto, or the sheets shown in Figs. 1 and 2 may be folded alongtwo parallel lines, such as those separating the base 2 from the sides 4 and 6, considering such lines as extending from edge to edge of the sheet, as shown, after which the opposite ends of such folded sheet maybe folded upon the base portion 2, so that the folded sheet occupies no greater area than the base 2.

The lines of scoring 15, 16 are provided, not only to permit the folding of the receptacleinto the position represented in Fig. 4, but to afford opposite pouring lips, the sides 4 and 6 being distended or bowed outward by the contents of the receptacle along the lines 15 and 16. 18, 19 and 20 are provided mainly to permit the folding of the receptacle into the position shown in Fig. 4.

It will be apparent that by the use of the bail 22, the members comprising the two wallsto which the same are attached are held in close engagement with each other.

It will be apparent that the folding of the walls of the receptacle in the manner indicated bring all free edges of the material to the upper end of the pail or receptacle, and that therefore no leakage of the material may occur between the walls 3 and 5 and the corner walls superimposed thereagainst. The bail 22 holds such superimposed corners closely in contact with the walls 3 and 8.

If desired, openings of any suitable type may be provided as at opposite sides of the openings 23 and 24 shown in Fig. 3, said openings being provided in the several members of the folding side Walls which meet in the manner described. If desired, eyelets may be'passed through and secured in such meeting openings in the manner described with respect to the modification shown in Fig. 5 and as illustrated at 23a, 23b (Fig. 6).

Preferably, as shown in Fig. 2, I provide the walls 3 and 5 with suitable flaps, 27 and 28, to be provided with openings corresponding to the openings 21 upon such sides. -Such fiaps when the receptacle is folded into shape for use, overlie the upper edges of the sides whereto the bail is attached and present their openings in line with the openings 23 and 24, so that the bail may be passed therethrough. If desired, such flaps vmay be provided with additional openings corresponding to the additional openings that may be provided upon said sides.. It will be apparent that by such construction the upper edge of each of the wallsto which the bail is attached will be securely bound together.

Having thus described one -type or embodiment of my invention, I desire it to be understood that although I have employed specific terms they are used in a descriptive or generic sense, the scope of the invention being set forth in the following claims.
